I'm betting you have in intermittent ground or +12V supply, not a bad mirror. When the light goes out, get a voltmeter on it. It'll be alot easier and cheaper to replace with a stock mirror if necessary.

Adding a aftermarket mirror is a relatively easy task, but I can imagine that you could find a stock dimming mirror off EBay or a bone yard -- probably for a lot less than a brand new dimming unit on EBay.

In the Spring I am going to be adding a GM dimming/compass mirror on my SE because it did not come with a dimming mirror nor was it a SSE/SSEi. I plan on running the wires down the A-Pillar and tapping of power from a switched source under the dash.

That sounds pretty cool..... I'm going to try to take my mirror off someday and see if I can determine the problem. I think it'* just bad contacts.... just kinda scared about pulling/ripping the mirror off. hehe
